Service time manipulations may or may not play in situations. Miranda might have been ready to step in on Opening Day last year, especially based on his preceding year in the minors, but I think service time was factored in to give him no shot in Spring Training. Royce Lewis was sent down, which coincidentally would rule him out from getting early arbitration status, but there were other factors in both cases. I don't think any team wants young players with high ceilings sitting on the bench accruing service time.
As far as whether to promote Kirilloff at this point, I would say that as a fit 25-year old, the only concern would be the wrist and if swinging a bat against 95 mph fastballs doesn't bother him, he should be in the major leagues. Paparesta has seemed to say that the medical end of his ramp up is complete. Let him play here and now if he is one of the best 13 position players.
